I am a Full Stack Developer with over 9 years of experience in the industry, working both on Web as well as native applications. While I excel at working with a team, having experienced managing a remote group of developers, I am also capable of single-handedly delivering projects from start to finish. With my skills and experience, I always strive to produce clean, robust and highly tested code for every project.
Having a very broad experience with numerous tools/languages and technologies, I specialize in building modern web applications and high-scale data processing pipelines.
My language of choice is Clojure.
Some of the technologies I've worked with in recent projects:

* Spark
* Storm
- Large and small client side applications in ClojureScript
